How we handle new build mastic in Belmont
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first, and if it is not put right, get in touch with us. If you have messy sealant that spoils new finishes and new-build shower sealant that has already split, we can put it right, on bathrooms & en suites, skirting & floors and show homes alike.
For a new home in or near Belmont, it’s worth checking the sealant early. Common snags include open skirting joints, lifting shower seals and gaps around frames.
Each job carries a 12-month guarantee, whatever its size.

New build mastic around Belmont
Belmont is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For new homes near Ore station, it’s worth checking the sealant early, while snags are still fresh.

What affects the cost of new build mastic
The quote reflects the job in front of us. We take into account:
- Mould in or behind the old joints
- Access and height
- The product the joint needs
- The old material and how stubborn it is
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- How we’d reach the joints
- If someone has resealed it before
- A few photos by email, if you can
- The address or postcode of the job
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved before giving you a price.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

Landlords, agents and businesses in Belmont
We work for landlords and letting agents as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
What happens on the day
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take anything from a few hours to several days, depending on the number of plots. For a job in Belmont, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Preparing for the visit
- Mention if the joints have been sealed before
- Keep children and pets away from the work area
- Mention any leaks or damp you’ve noticed

Advice
Do you need new build mastic in Belmont?
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints aren’t always given time to dry first.
It’s worth asking for a quote if you see:
- Gaps opening as the house dries out and settles
- Cracked sealant around new window and door frames
- Beads laid onto grit and dust from the build
- Sealant work across a run of new homes
Around Belmont, as everywhere, new build mastic is only as good as the preparation behind it.
What to look for in a quote
- What happens if they find a problem under the old sealant
- What product goes in the joint
- How long the guarantee is
- What preparation is included
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Open a window or run the fan after bathing
- Keep water off fresh sealant until it has cured
- Resist patching a failed seal with a tube from the DIY shop
- Avoid scourers and strong chemicals on sealant
Leave the sealant for the cure time we give you before showering or bathing. Silicone is normally left for about a day before water reaches them.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you, so raise it early.
When it is not the sealant
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Your warranty claim itself, which is between you and the builder
- Cracking that points to a structural problem
- A tray or bath that isn’t properly supported, until it’s fixed
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.
